Compare any two graphics cards:
GeForce GTX 780 Ti vs Nvidia Titan X
IntroThe GeForce GTX 780 Ti features a core clock frequency of 875 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.
Compare all that to the Nvidia Titan X, which features core clock speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X RAM. It features 3584 SPUs along with 224 TAUs and 96 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
As far as performance goes, the Nvidia Titan X should in theory be a lot superior to the GeForce GTX 780 Ti overall. (explain)
Texel RateThe Nvidia Titan X should be a lot (about 51%) more effective at anisotropic filtering than the GeForce GTX 780 Ti. (explain)
Pixel RateThe Nvidia Titan X is much (more or less 224%) better at full screen anti-aliasing than the GeForce GTX 780 Ti, and also will be able to handle higher screen resolutions without losing too much performance. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
